RADIUS Application filed June 9, 1922. Serial No. 56?,M6.

To aZZ whom it may concern:

Be it known that I, Her H. Manson, a citizen of the United States, residing at Rochester, in the county of h lonroe and State of New York, have invented certain new and useful Improvements in Radiojachs, of which the following is a full, clear, concise, and exact description.

This invention relates to one portion of a connection terminal which is commonly known in the art as a jack and which is arranged to cooperate with the other portion of a connection terminal commonly known as a plug".

Such jacks are usually mounted in a panel or other supporting frame and it frequently happens that the jack is used with panels of various thicknesses so that it becomes necessary to design it for use in such panels. Furthermore, the front end of the jack is exposed to view and it is important that this portion of it present a finished appearance. It is also necessary that a fixed distance be maintained between the front end of the jack and the terminal springs supported thereby, in order that proper contactmay be made between the various portions of the jack and a cooperating plug.

It has been proposed to provide the frame of the jack with an apertured lug through which a screw or bolt passes to connect it to the panel but this places all the strain and support of the jack on a small portion of the panel, with the result that frequently panels are broken or the jacks are continually becoming loosened by use. Furthermore this arrangement is undesirable since the head of the fastening belt or screw is visible at the front of the panel.

A; second arrangement has been proposed in which the sleeve portion. of the jack is screw-threaded to screw into an opening); in the end of the jack, but in this arrangement a fixed distance cannot be maintained between the end of the sleeve and the cooperating springs of the jack unless washers are used. Since these washers and the panels are not uniform in thickness it is difficult to properly assemble such a jack.

In accordance with. the present invention it is proposed to provide a jack in which the springs will always be at a fixed distance from the end of the sleeve and in which the jack. may be readily screwed to the panel without weakening the same and still present a finished appearance.

These features will appear from the drawings in which Fig. 1 is a side view of the improved jack; Fig. 2 is a section through the jack anc panel; while Figs. 3 and show the sleeve of the jack mounted in panels of two different thicknesses.

The numeral 5 generally designates the frame of the jack which consists of a sheet of metal bent at right angles along its center line to form two side members 6 and 7, while an extensi on of the side member Y apertured and bent upwardly at right angles, is secured to the side member 6 in any suitable manner as by spot-welding. The side member 7 serves as a support for the spring assembly generally designated 9 which consists principally of a crimped tip spring 10 and a crimped ring spring 11, with cooperatingcontact springs. A. sleeve 12 provided with a shoulder 18, has one of its ends secured in the aperture in the member 8 in any suitable manner as by staking with the end member 8 of the frame against the face of the shoulder 13. The other end of the sleeve 14 is threaded. but it should be noted that the threads are absent from the extreme ends of the sleeve as indicated at to present a finished appearance.

In assembling the jack in an apertured panel, the threaded portion of the sleeve 12 is inserted in the aperture until the panel engages the shoulder 13, whereupon the nut 16 is tightened until the jack is firmly fixed to the panel. It will be noted in Fig. i that where a very thick panel is used, the nut16 is almost flush with the end of the sleeve of the ack. In 2 where a thinner panel is used still more of the end of the sleeve is visible, while in Fig. 3 where a very thin panel is used, a still greater portion of the sleeve is visible, but this is immaterial since the end of the sleeve is smooth and presents a finished appearance.

It will be found in practice that it is desirable to have the panel 17 engage the shoulder 13 of the sleeve instead of engaging the end member 8 of the frame, since if this last arrangement is used the tightening of the nut 16 against the panel may loosen the sleeve 12 from the jack frame.

lVhat is claimed is 1. In an article of the class described, a frame having an apertured upturned end, terminal springs mounted on said frame adjacent said aperture, a hollow sleeve having a raised annular shoulder intermediate its ends, one end of said sleeve being staked in said aperture with its shoulder engaging said frame. threads formed on said sleeve but spaced from the free end thereof, and a nut engaging said threads.

2. In an article of the class described, a frame comprising an apertured end portion and two side portions, said side portions being disposed at right angles to each other and to said end portion, a spring assembly mounted on said frame adjacent said end portion, a hollow sleeve provided with a raised shoulder intermediate its ends, one end of said sleeve being staked in said aperture with its shoulder engaging said frame, threads on said sleeve portion spaced from the free end thereof, and a nut engaging said threaded portion.

3. In an article of tie class described, a frame having an apertured upturned end, terminal springs mounted on said frame adjacent said aperture, a hollow sleeve having a shoulder, said sleeve being secured to said frame in said aperture. threads formed on said sleeve, but spaced from the free end thereof, and a relatively thick nut engaging said threads.

4. The combination with a panel having an opening therein, a hollow sleeve provided with threads spaced a substantial distance from one end thereof, said sleeve being inserted in said opening. a frame secured to other end of said sleeve, terminal springs insulatedly mounted on said frame. and a nut of substantial thickness to engage said threads whereby said frame is secured to said panel with the threaded portion of said sleeve concealed.

5. The combination with a panel having an opening therein, a hollow sleeve pro vided with a shoulder, said sleeve being provided with a threaded portion spaced from its ends and at one side of said shoulder, the threaded portion of said sleeve being inserted into said opening with the shoulder engaging said panel. an apertured frame provided with a spring assembly, one end of said sleeve being inserted in the aperture in said frame and secured in position with said frame abut ting said shoulder, and a tapered nut engaging said threaded sleeve to hold said shoulder against said panel and to conceal said threaded portion.

In witness whereof, I hereunto subscribe my name this 5th day of June A. D. 1922.
